Safe
for ozone action days.
Converting small utility engines such as lawnmowers
to burn propane instead of gasoline can reduce emissions
of ozone precursors by one third and increase fuel economy
by 14 percent (Cotton, 1992). According to the U.S.
Environmental Protection Agency, a typical four-horsepower
gasoline lawnmower engine generates almost six times
as much volatile organic compounds (VOCs) per hour of
use as a typical car.
Clean
enough to use indoors. LPG forklifts
can reduce emissions of indoor and urban air pollutants,
especially emissions of particulate matter compared
to diesel and carbon monoxide compared to gasoline.
“Overall, the urban air-quality benefits of LPG are
similar to the benefits of CNG (generally considered
the cleanest of the fossil-fuel alternatives.)” (Delucchi,
1999).
